All Hawk Performance Performance Ceramic brake pads provide a limited lifetime warranty, ensuring products to be free of defects from manufacturers workmanship and materials.Note: Hawk Performance burnishes its High Performance Street brake pads as a final step in the factory, but all brake pads have to be bedded-in with the rotors (new or used) that they will be used against. Properly bedding-in new brake pads results in a transfer film being generated at the pad and rotor interface to maximize brake performance.
